I.
INTRODUCTION
Conspicuously absent from Robinhood’s opposition to the instant motion is any
response to the premise underlying Plaintiffs’ argument, to wit, the gravamen of Plaintiffs’
two market manipulation claims is Robinhood’s actions – its PCOs and cancellations –
not its statements. ECF 668 at 4-5. Whether or not an investor read or heard any of
Robinhood’s statements, when they sold stock after Robinhood removed significant
demand from the market, driving down prices, they were injured.1 Conversely, no Rule
10b-5(b) claim could exist absent the manipulative acts: if Robinhood had not imposed
PCOs or cancelled purchase orders for millions of shares, Robinhood would have had no
reason to discuss “market volatility” or the state of its liquidity.
Because market manipulation class actions are rare, the Eleventh Circuit has not
addressed the application of the Affiliated Ute presumption in this context.2 This Circuit
had spoken, however, on its application in Rule 10b-5(b) cases, most notably in
Huddleston v. Herman & MacLean, 640 F. 2d 534, 539, 543 (5th Cir. 1981) (“The issues
that now concern us focus on statements made in the TIS prospectus.”) and Cavalier
Carpets, Inc. v. Caylor, 746 F.2d 749, 753 n.16 (11th Cir. 1984) (setting forth the elements
of a Rule 10b-5(b) claim in a case involving a misrepresentations and omissions in the
context of a business deal). Because Robinhood had not silently undertaken its
manipulative actions, the Court held that it was bound by the “Huddleston rule” and
refused to apply the Affiliated Ute presumption of reliance in a “mixed case” involving
both misstatements about Robinhood’s liquidity and omissions from its “market
volatility” blogpost on the morning of January 28, 2021. ECF 622 at 47-48. Now that

1 Plaintiffs’ expert has calculated the per-share damages caused by Robinhood’s removal
of its customers’ demand for each of the Affected Stocks for each day of the class period.
2 The Court noted that the Eleventh Circuit had not taken a position on whether Affiliated
Ute Citizens v. United States, 406 U.S. 128 (1972), could only apply in Rule 10b-5(b) cases,
as the Ninth Circuit had ruled in Desai v. Deutsche Bank Sec. Ltd., 573 F.3d 931, 940 (9th
Cir. 2009). ECF 622 at 44-45. Although the Supreme Court’s decision in Macquarie
Infrastructure Corp. v. Moab Partners, L.P., 601 U.S. 257, 259-60 (2024), upends Desai,
Robinhood repeats its Desai argument. Compare ECF 675 at 15 with ECF 568 at 32
(Plaintiffs “‘cannot avail themselves of the Affiliated Ute presumption’ permitted in
omissions cases”). The Court’s skepticism was warranted. ECF 622 at 45 (it would be
“bizarre” if a presumption that arose in a Rule 10b-5(a)&(c) case could not apply in one).
Case 1:21-md-02989-CMA   Document 676   Entered on FLSD Docket 05/23/2024   Page 6 of 17

2
Macquarie has eliminated the concept of a pure omissions case under Rule 10b-5(b), the
distinction upon which the “mixed case” rule is based is no longer viable.
Unable to grapple with this change of law, Robinhood’s arguments are hopelessly
inconsistent. Asserting that Macquarie – a Rule 10b-5(b) case in which the plaintiffs
alleged omissions from and misrepresentations in SEC filings – has no application to a
Rule 10b-5(a)&(c) market manipulation action, Robinhood argues that Plaintiffs “do not
even assert a claim under Rule 10b-5(b).” ECF 675 at 13. Yet Robinhood maintains the
applicability of Huddleston to this case – even as Robinhood describes Huddleston as
brought under “‘the second subparagraph of the Rule’ (i.e., Rule 10b-5(b)), unlike
Affiliated Ute which involved ‘the first or third subparagraph of the Rule’ (i.e., Rule 10b-
5(a) or (c)). 640 F.2d at 548.”  ECF 675 at 11 & n.4. Finally, Robinhood contends that
Affiliated Ute only applies to “pure omissions theories under Rule 10b-5(a) and Rule 10b-
5(c).” ECF 675 at 14. This ignores the fact that Affiliated Ute expressly affirmed the lower
court’s finding of a Rule 10b-5(b) violation. 406 U.S. at 152. Thus, Affiliated Ute itself
instructs that claims under Rule 10b5-(a)&(c) and Rule 10b5-(b) can coexist without the
former being transformed into the latter simply because defendants do not remain silent.

Perhaps recognizing the inherent difficulty, after Macquarie, of continuing to
press application of a Rule 10b-5(b) standard limiting the invocation of the Affiliate Ute
presumption of class-wide reliance to pure omissions cases, Robinhood relies primarily
on inapposite procedural arguments to urge denial of the motion. ECF 675 at 5, 7-10.
First, its assertion that the motion is untimely ignores that the Court has broad discretion
to reconsider a non-final order at any time before judgment, especially class certification
under Rule 23(c)(1)(C). Next, Robinhood mischaracterizes this motion as a new class
certification motion filed in violation of the scheduling order. Not so. Plaintiffs sought
leave to file a renewed motion with expert analysis of price impact – and, later, loss
causation and damages, based upon massive quantities of Robinhood and FINRA data3 –
but on April 19, 2024, the Court denied Plaintiffs permission to file. ECF 665. The instant

3 Because of Robinhood’s considerable difficulty querying its data lake for, at that point,
more than 18 million of lines of responsive data, and the many months it took FINRA to
compile more than two trillion bytes of data, ECF 619-2 at 2-3, ¶¶10-14, the Court granted
a 3-month extension of the merits expert report exchange deadlines. ECF 621 at 2. This
allowed Plaintiffs’ expert to add loss causation and per-share damages analyses.
Case 1:21-md-02989-CMA   Document 676   Entered on FLSD Docket 05/23/2024   Page 7 of 17

3
motion contains no new evidence and is limited to asking the Court to reconsider its
earlier ruling based upon a Supreme Court decision handed down on April 12, 2024.
Finally, because this motion seeks to “permit maintenance of a class action,” it is exempt
from Local Rule 7.1(a)(3)’s meet and confer requirement, with which Plaintiffs have
heretofore complied.4

In the interests of justice for investors injured by Robinhood’s unprecedented
restrictions, Plaintiffs respectfully request the Court permit invocation of a class-wide
presumption of reliance on Robinhood’s manipulative actions and grant certification.
II.
ARGUMENT
A.
This Reconsideration Motion Is Timely and Procedurally Proper
Robinhood’s opposition tries to deflect from the substantive strength of Plaintiffs’
motion with claims that it violates the scheduling order as well as the Federal and Local
Rules. These efforts are for naught because both the law and facts demonstrate the motion
is properly before the Court.
1. The Court has discretion to reconsider non-final orders

“It is permissible for a district court to rescind its own interlocutory order.” Harper
v. Lawrence Cty., 592 F.3d 1227, 1231 (11th Cir. 2010) (court properly reconsidered its
prior conversion of some defendants’ Fed. R. Civ. P. (“Rule”) 12(b)(6) motion to a Rule 56
motion) (citing cases); Region 8 Forest Serv. Timber Purchasers Council v. Alcock, 993
F.2d 800, 806 (11th Cir. 1993) (abuse of discretion standard applies where non-final order
is reconsidered). One court in this District recently held:
[T]he Supreme Court has been clear that “every order short of a final decree
is subject to reopening at the discretion of the district judge.” Moses H. Cone
Mem'l Hosp. v. Mercury Constr. Corp., 460 U.S. 1, 12, 103 S. Ct. 927, 74
L.Ed.2d 765 (1983); see also Dietz v. Bouldin, 579 U.S. 40, 46, 136 S. Ct.
1885, 195 L.Ed.2d 161 (2016) (“[T]he Court has recognized that a district
court ordinarily has the power to modify or rescind its orders at any point
prior to final judgment in a civil case.”). Because we think the prior order
was wrong, we’re well within our discretion to correct it.
Great Lakes Ins. SE v. Crabtree, 673 F. Supp. 3d 1301, 1311 n. 20 (S.D. Fla. 2023). Given
the Supreme Court’s broad mandate of discretion to review non-final orders, Robinhood’s
assertion that the inapplicability of Rules 59(e) and 60(b) leaves Plaintiffs without a

4 See, e.g., ECF 565 at 15; ECF 587 at 8; ECF 605 at 15; and ECF 624 at 3.
Case 1:21-md-02989-CMA   Document 676   Entered on FLSD Docket 05/23/2024   Page 8 of 17

4
remedy has been rejected by courts across the country. Because a higher bar applies to
Rule 59(e) and 60(b) motions, to preserve the finality of judgments, “the result of a
determination that Rule 59(e) and Rule 60(b) are inapplicable to the present motion …
actually means that the court has more, not less, discretion to alter or amend the ruling,”
Laird v. Stilwill, 982 F. Supp. 1345, 1354 (N.D. Iowa 1997) (emphasis in original); SSL,
Inc. v. Scottsdale Ins. Co., No. 4:16-00324-CV-W-HFS, 2017 WL 6383988, at *1 (W.D.
Mo. Oct. 18, 2017); M.G. v. Armijo, No. 1:22-cv-00325, 2024 WL 810370, at *4 (D.N.M.
Feb. 27, 2024) (“no limit or governing standard” on ability to reconsider class
certification).
In fact, Robinhood’s argument that a motion for reconsideration must comply with
either Rule 59(e) or Rule 60(b) (ECF 675 at 7-8) misconstrues the law of this Circuit. The
sole authority provided, Silva v. United States Att'y Gen., No. 18-21521-CIV, 2019 WL
10784381, at *1 (S.D. Fla. May 28, 2019) (ECF 675 at 7), cites Alcock, 993 F.2d 800 (11th
Cir. 1993), for that proposition. However, Alcock does not impose such a requirement on
motions for reconsideration:
This Court has never explicitly considered the standard of review to be
applied to a district court's grant of a motion for reconsideration of a non-
final judgment.4 However, when reviewing a district court’s disposition of a
motion for reconsideration after final judgment,5 we have consistently
stated that the decision to grant such relief is committed to the sound
discretion of the district judge and will not be overturned on appeal absent
an abuse of discretion. [Citation to Rule 59(e) and Rule 60(b)
reconsideration cases]. We see no reason to apply a different standard when
the party seeks reconsideration of a non-final order.
993 F.2d 800, 805-06 (footnotes in original). In note 4, the court refers to Rule 54(b) as
governing motions for reconsideration of non-final orders, to wit, “any order or form of
decision, however designated, which ... is subject to revision at any time before the entry
of judgment.” In note 5, the court refers to Rules 59(e) and 60(b) as governing motions
for reconsideration “made after final judgment.” 993 F.2d at 805-06 nn. 4 and 5. Thus,
Silva and Morales v. Charlotte Corr. Inst., No. 18-22787-CV, 2023 WL 5593375, at *1-2
(S.D. Fla. May 4, 2023), cases in which motions were made following dismissal, are
inapposite.5

5 Robinhood’s effort to distinguish Plaintiffs’ cases (ECF 675 at 9) does not address the
import of Macquarie being decided months after Rule 59(e)’s 28-day deadline expired.

 2. The instant motion is not a renewed certification motion
Citing two cases, Robinhood argues that the Court cannot revisit its non-final order
under Rule 23(c)(1)(C), and that the instant motion is an improper renewed certification
motion in violation of the scheduling order. ECF 675 at 8.  While Daniel F. v. Blue Shield
of California, No. C 09-2037 PJH, 2015 WL 3866212 (N.D. Cal. June 22, 2015) and In re
Lithium Ion Batteries Antitrust Litig., No. 13-MD-02420, 2018 WL 4215573 (N.D. Cal.
Sept. 4, 2018), are strikingly similar to each other, they bear no resemblance to this case.
In those two cases: (a) many months after the denial of class certification – for the
second time in Lithium Ion – without notice, plaintiffs filed unauthorized new motions
for class certification on the deadline for dispositive motions, even though new scheduling
orders had been entered based upon prosecution on behalf of individual plaintiffs (Daniel
F., 2015 WL 3866212, at *2; Lithium Ion, 2018 WL 4215573 at *1-2); (b) neither motion
was justified by changes in law or new evidence (Daniel F., 2015 WL 3866212 at *3-4:
“[Plaintiffs] are seeking not reconsideration of the prior order denying class certification,
but rather a new ruling on a motion ... They concede that there is no material difference
in the law, and argue only that the revised class definition and the copies of transcripts of
deposition testimony constitute ‘new facts.’”; Lithium Ion, 2018 WL 4215573 at *3: “IPPs
now seek to certify a narrower class, relying upon the same methodologies and same
transactional sales data used by their expert in the prior motions …[, they] offer no
‘changed circumstances.’ The addition of testimony from company representatives that
could, with the exercise of reasonable diligence, have been offered earlier, does not alter
the analysis.”); and (c) motion did not fall within court’s discretion under Rule 23(c)(1)(C)
to reconsider the prior order based on newly discovered evidence, clear error, or an
intervening change in the controlling law. Lithium Ion, 2018 WL 4215573 at *4; Daniel
F., 2015 WL 3866212, at *3 (“the ‘renewed’ motion does not mention Rule 23(c)(1)(C) …
plaintiffs simply repeat arguments they previously made”).

Wholly unlike Daniel F. and Lithium Ion, Plaintiffs did not ambush defendants
and the Court with a last-minute unauthorized certification motion that would upend pre-
trial scheduling tailored to individual trials. The chronology of events establishes the exact
opposite to be true. Because of difficulties in compiling huge volumes of trading data for
expert analysis, the scheduling order was amended on November 9, 2023, to extend
expert report deadlines (ECF 621), days before the Court denied class certification. ECF
Case 1:21-md-02989-CMA   Document 676   Entered on FLSD Docket 05/23/2024   Page 10 of 17

6
622. In December 2023, interpreting the Court’s denial without prejudice to have invited
a new motion with proof of price impact caused by Robinhood’s PCOs and cancellations,
after consulting with Robinhood, Plaintiffs filed an unopposed motion seeking a briefing
schedule to run concurrent with fact and expert discovery, between February 15 and May
15, 2024, which would not require further amendment to the scheduling order. ECF 624
at 1. Plaintiffs drafted papers, including an expert analysis demonstrating price impact
(and, after discovery concluded, loss causation and per-share damages for each claim),
but awaited Court approval to file. After permission to file a renewed motion was denied
on April 19, 2024, the instant motion was filed, seeking reconsideration based upon a
change of law on April 12, 2024.6 As authorized by Rule 23(c)(1)(C), the instant motion
properly seeks reconsideration based upon Macquarie removing the “pure omissions”
category of cases underpinning  the Court’s Affiliated Ute analysis.
3.  Local Rule 7.1(a)(3) exempts class certification from the pre-
motion meet and confer requirement
Local Rule 7.1(a)(3) provides: “Prior to filing any motion in a civil case, except a
motion … to permit maintenance of a class action, counsel for the movant shall confer …
with all parties or non-parties who may be affected by the relief sought in the motion in a
good faith effort to resolve by agreement the issues to be raised in the motion.” (Emphasis
supplied.) Because no Local Rule governs motions for reconsideration, and the relief
sought is to “permit maintenance of a class action,” Plaintiffs understood Local Rule
7.1(a)(3) to exempt this motion from the conference requirement – with which Plaintiffs
have consistently complied. See n. 4, supra (citing four motions); see also A Aventura
Chiropractic Ctr., Inc. v. Med Waste Mgmt. LLC, No. 12-21695-CIV, 2013 WL 3463489
(S.D. Fla. July 3, 2013) at ECF 114 (successful motion for reconsideration of a denial of
class certification was filed without a certificate of compliance).

None of the cases cited by Robinhood to argue otherwise involved exempt motions.

Procedural attacks on reconsideration motions most often argue that the movant
is recycling old arguments or merely disagrees with the court. Robinhood does not.7 The
propriety of the motion is underscored by the absence of these common tropes.
B.
Macquarie Changed the Law Upon Which The Court Relied
Despite the fact that Robinhood quotes Huddleston for the proposition that it is a
Rule 10b5-(b) case and not a Rule 10b-5(a)&(c) case, ECF 675 at 11 n.4, Robinhood
continues to press the Court to apply the “mixed case rule of Huddleston” here, even
though Robinhood agrees that Plaintiffs have not pled Rule 10b-5(b) claims. ECF 675 at
13. After Macquarie held there are no pure omissions cases under Rule 10b5-(b), the
“mixed case rule of Huddleston” – which formed the analytic framework the Court
believed prevented invocation of the Affiliated Ute presumption because Robinhood did
not remain silent – is no longer valid. Robinhood’s arguments do not persuade otherwise.
1. After Macquarie, The Court Is No Longer Restricted by the
“Mixed Case Rule of Huddleston”
In its class certification opinion (ECF 622 at 46), the Court noted “there is no
denying the similarities between this case” and In re Barclays Liquidity Cross & High
Frequency Trading Litig., 390 F. Supp. 3d 432 (S.D.N.Y. 2019). In In re Barclays, the
gravamen of the case was a manipulative scheme by which stock exchanges sold
sophisticated products to high-frequency trading firms which enabled them to secretly
front-run trades to other investors’ detriment. The court held that the Affiliated Ute
presumption could apply even though the exchanges also made materially misleading
public statements which described the products available for purchase while omitting

7 The most Robinhood could muster was a footnote claiming that Plaintiffs (in footnotes)
had argued only that the Court had erred. ECF 675 at 12 n.5.
Case 1:21-md-02989-CMA   Document 676   Entered on FLSD Docket 05/23/2024   Page 12 of 17

8
their impact on trading. ECF 622 at 46 (citing In re Barclays, 390 F. Supp. 3d at 448).
Nonetheless, the Court explained, the Eleventh Circuit’s holdings in Cavalier Carpets and
Huddleston take “a more restrictive approach when cases involve both misstatements and
omissions.” ECF 622 at 46.  Specifically, where misstatements and omissions are alleged,
the “‘mixed case rule of Huddleston’ applied and Affiliated Ute did not.” Id. at 47 (quoting
Cavalier Carpets).8 The Court concluded: “The Court is bound by these decisions.” Id.
Now that the Supreme Court has ruled there are no pure omissions cases under Rule 10b-
5(b), the  premise upon which “mixed case rule of Huddleston” was based, that limited
the application of Affiliated Ute to pure omissions cases, no longer binds the Court.
2. Affiliated Ute is applied in securities fraud cases in which a
fiduciary duty is not alleged
Macquarie involved nondisclosure in a public company’s SEC filings. To argue that
Macquarie “has no relation to Affiliated Ute” and its progeny (ECF 675 at 12), Robinhood
claims that the Eleventh Circuit limits the application of Affiliated Ute to cases in which
someone with a fiduciary duty stood silent. ECF 675 at 12. However, the phrase “fiduciary
duty” does not appear in Affiliated Ute. In fact, after Cavalier Carpets, courts in this
Circuit have evaluated whether the “mixed case rule of Huddleston” would preclude
application of the Affiliated Ute presumption in securities fraud cases where no fiduciary
duty was alleged. See Hamilton Partners, Ltd. v. Sunbeam Corp., No. 99-CV-8275, 2001
WL 34556527, at *12 (S.D. Fla. July 3, 2001); Walco Invs., Inc. v. Thenen, 168 F.R.D. 315,
330-31 (S.D. Fla. 1996); In re Amerifirst Sec. Litig., 139 F.R.D. 423, 430 n.4 (S.D. Fla.
1991); see generally Loc. 703, I.B. of T. Grocery & Food Emps. Welfare Fund v. Regions
Fin. Corp., 762 F.3d 1248, 1248, 1256 (11th Cir. 2014) (praising the “wisdom” of the
district court’s application of Affiliated Ute to analogize a confirmatory misrepresentation
with a “traditional omission”).

8 Cavalier Carpets raised a unique concern in Rule 10b5-(b) cases, not present here: “We
also note the practical problems of a dual jury instruction on reliance on a securities fraud
case where both alleged misstatements and omissions are present and the probability of
jury confusion. A dual instruction would require the jury ‘to search for proof of reliance
by the plaintiff with regard to the misrepresentations, and to search for proof of
nonreliance by the defendant with regard to the omissions.’” 746 F.2d at 757; see also
Becks v. Emery-Richardson, Inc., No. 86-6886, 1990 WL 303548, at *20 (S.D. Fla. Dec.
21, 1993) (citing Cavalier Carpets). Here, burden-of-proof shifting instructions can be
avoided because misrepresentations and omissions are not elements of Plaintiffs’ claims.

 Robinhood characterizes the premise of Plaintiffs’ motion as “absurd” because the
Supreme Court would not have sub silentio “dramatically altered the meaning of
Affiliated Ute and overruled … Cavalier Carpets and Huddleston …” ECF 675 at 13.
However, it is Robinhood’s argument that rests on the incorrect premise that Affiliated
Ute has only been applied when a defendant with a fiduciary duty to speak stood silent.
For this reason, Macquarie has undercut the “mixed case rule of Huddleston” which has
been applied to limit the application of Affiliated Ute.9
3. Affiliated Ute is not “premised on pure omissions theories”10
Robinhood makes a straw-man argument that Plaintiffs’ reading of Macquarie
would appear to render Affiliated Ute a nullity. ECF 675 at 14. To reconcile Affiliated Ute
and Macquarie, without conceding the former applies to this case, Robinhood asserts that
it continues to apply in Rule 10b-5(a)&(c) cases that are “premised on pure omission
theories.” ECF 675 at 14. Robinhood then contends that it cannot apply here because
Plaintiffs’ market manipulation claims are premised on “mixed allegations of
misstatements and omissions.” Id. Not so. The claims are based on actions, to wit, PCOs
and cancellations, and the Court has already held that Robinhood can be held liable for
undertaking such actions with scienter even if it said nothing at all.  ECF 503 at 24, 51.
Moreover, as Robinhood appears to concede (by its use of the alternative test
“purely, or primarily, from omissions”) (ECF 675 at 14), the mere presence of
misstatements does not deprive class plaintiffs of the ability to invoke Affiliated Ute.

9 Apparently uncertain about this Circuit’s standard, Robinhood elsewhere argues that a
duty to speak must exist, not necessarily a fiduciary duty. ECF 675 at 11. If so, courts have
held that engaging in misconduct that amounts to market manipulation under Rule 10b-
5(a)&(c) gives rise to a duty to disclose. See, e.g., MAZ Partners LP v. First Choice
Healthcare Solutions, Inc., No. 6:19-cv-619, 2019 WL 5394011, at * 6, 11 (M.D. Fla. Oct.
16, 2019), report and recommendation adopted, 2020 WL 1072582, at *5 (M.D. Fla. Feb.
14, 2020) (Rule 10-5(b) claim stated where manipulative scheme under Rule 10b-5(a)&(c)
not disclosed); In re Initial Pub. Offering Sec. Litig., 241 F. Supp. 2d 281, 381 (S.D.N.Y.
2003); In re UBS Auction Rate Sec. Litig., No. 08 CIV. 2967, 2010 WL 2541166, at *27
(S.D.N.Y. June 10, 2010) (citing IPO); S.E.C. v. Santos, 355 F. Supp. 2d 917, 920 (N.D. Ill.
2003) (same). As in Affiliated Ute, where the bank employees should have disclosed their
financial interest in creating a market to resell tribe members’ shares for a profit,
Robinhood’s manipulative actions for its own financial interest created a duty to disclose
critical facts the Court found Robinhood to have omitted. ECF 503 at 45-46.
10 See ECF 675 at 14.
Case 1:21-md-02989-CMA   Document 676   Entered on FLSD Docket 05/23/2024   Page 14 of 17

10
Indeed, in Affiliated Ute itself, the Supreme Court found Rule 10b-5(a)&(c) violations
while also upholding a finding that the bank employees had violated Rule 10b5-(b):
“Clearly, the Court of Appeals was right to the extent that it held that the two employees
had violated Rule 10b-5 … the record reveals a misstatement of a material fact, within the
proscription of Rule 10b-5(2), namely, that the prevailing market price of the UDC shares
was the figure at which their purchases were made.” 406 U.S. at 152. As Rule 10b-5(b)
claims are not even alleged here, Robinhood’s misstatements and omissions cannot
preclude the application of Affiliated Ute to its manipulative actions.
4. Plaintiffs’ §9(a)(2) Claim is Susceptible to Class-wide Proof
Robinhood’s argument concerning the continued application of Affiliated Ute in
cases arising “purely, or primarily, from omissions,” ECF 675 at 14, supports certification
of the §9(a)(2) claim. In particular, Robinhood does not dispute that it was silent with
respect to its cancellation of purchase orders for millions of shares of the Affected Stocks.
ECF 675 at 15.
Robinhood instead asserts that because Macquarie did not involve a §9(a)(2)
claim, a motion for reconsideration based upon that decision cannot lie. ECF 675 at 15.
Having held that reliance was an element of both claims alleged, the Court determined it
could “apply the principles of reliance under section 10(b) to the section 9(a)(2) claim.”
ECF 622 at 39. While the legal principles may be the same, the facts with respect to the
two claims are not. Because Macquarie knocked the legs out from under the analytic
framework supporting the “mixed case Huddleston rule” that the Court had applied to
both claims, Plaintiffs respectfully submit that Robinhood’s silence with respect to its
purchase order cancellations allows Plaintiffs to invoke the Affiliated Ute presumption
with respect to their §9(a)(2) claim.
III.
 CONCLUSION
For the reasons stated above and in the opening memorandum of law, Plaintiffs
respectfully request that the Court reconsider its original ruling and grant class
certification of both of Plaintiffs’ claims.
